China to be Site of First Commercial Implementation of TRIG Coal Gasifier
Beijing Guoneng Yinghui Clean Energy Engineering Co., Ltd. (Beijing Guoneng) has awarded KBR a contract to provide licensing, engineering services and proprietary equipment for the implementation of KBR's and Southern Company's Transport Integrated Gasification technology (TRIG) at a power plant operated by Dongguan Tianming Electric Power Co., Ltd. (Dongguan TMEP) in Guandong Province, Peoples Republic of China.

The contract award marks China as the site for the first worldwide commercial implementation of the TRIG technology with the goal of producing low-emission, coal-based electricity. TRIG coal gasification technology was co-developed developed by Southern Company, KBR Inc., and others including the US Department of Energy (DOE), at the DOE's research facility in Wilsonville, Ala., that is managed and operated by Southern Company.

IGCC IGCC plants use two power cycles, extracting more electricity from a tonne of coal.

At the Dongguan TMEP facility, TRIG technology will be added to an existing gas turbine combined cycle plant so that it can use synthetic gas from coal as its fuel for generating electricity, rather than fuel oil.

The 120-megawatt Dongguan TMEP plant, expected to begin operation in 2011, would demonstrate an example of advanced US IGCC (integrated gasification combined cycle) technology that is being developed in partnership between the DOE and industry. This IGCC technology is compatible with carbon capture, and its deployment in China is a step toward positioning IGCC for future integration with carbon capture technology.

Southern Company subsidiary Mississippi Power currently is seeking regulatory approval to build a 582-megawatt plant using TRIG technology in Kemper County, Miss. That plant would include 65% carbon capture and sequestration. Read full article
